DSP LLE: MAJOR LLE revamp. Interpreter/JIT infrastructure done. Still left to mix and match the correct functions to the correct instruction hexcodes. More changes:

Browse Source 
-Tagged unimplemented instructions and FIXME instructions in the DSP interpreter header
-Expanded the DSP instruction union to be viewable as helpful instruction structures
